How to Fix Common iTunes Errors on Windows
iTunes has long been Apple’s go-to software for managing music, apps, and devices. While it works flawlessly on macOS, Windows users often encounter frustrating errors when installing, updating, or syncing iTunes. These issues typically occur due to missing components, outdated system files, incompatible drivers, or conflicts with other software.
Windows and iTunes communicate through multiple background processes like Apple Mobile Device Service (AMDS) and Bonjour. If any of these services fail or crash, errors appear. Additionally, Windows security tools, registry problems, or corrupted installation files can also cause iTunes to misbehave.
Whether your iTunes won’t open, refuses to sync your iPhone, or fails to update, this guide walks you through proven fixes to restore stable performance on Windows.
Most Common iTunes Errors on Windows
Before diving into solutions, let’s understand the most frequent issues Windows users face:
1. Installation or Setup Errors
These occur during installation or update, often with messages like:
- “Error 2: Apple Application Support was not found.”
- “Windows Installer package problem.”
2. Launch or Startup Errors
You may see:
- “iTunes cannot open because some required files are missing.”
- “MSVCR80.dll missing.”
3. Syncing Problems
Common during iPhone or iPad connection:
- “iTunes cannot detect your device.”
- “Error 0xE80000A.”
4. Update or Restore Failures
When updating iOS or restoring backups:
- “Error 3194,” “Error 17,” or “Unknown error occurred.”
5. Freezing, Crashing, or Slow Performance
These often result from corrupted preferences, outdated components, or Windows permission issues.
Understanding the error type helps you apply the most effective fix.
Fix 1: Update iTunes and Windows
An outdated iTunes version is one of the main reasons behind most errors. Apple regularly releases updates to fix compatibility issues with Windows builds.
Steps to Update iTunes:
- Open iTunes → Click Help > Check for Updates.
- If you installed iTunes from the Microsoft Store, updates will appear automatically via the Store’s “Library” tab.
- Restart your PC after updating.
Update Windows:
- Press Windows + I → go to Windows Update.
- Click Check for updates and install all pending patches.
- Restart your computer.
Pro Tip: Always keep both iTunes and Windows updated together. Compatibility issues between older iTunes versions and new Windows builds cause most startup and connection errors.
Fix 2: Repair iTunes Installation
If you recently updated or moved iTunes files, the installation might have become corrupted. Instead of reinstalling immediately, try repairing it.
Steps to Repair iTunes on Windows:
- Open Control Panel → Programs → Programs and Features.
- Find iTunes in the list.
- Right-click and choose Repair (or select it and click Repair from the top menu).
- Allow the repair wizard to finish, then restart your computer.
If you have Apple components installed separately (like Apple Mobile Device Support, Bonjour, or Apple Application Support), repair them individually in the same window.
Note: Do not uninstall before attempting repair — it preserves your settings and library.
Fix 3: Reset iTunes Settings
Sometimes, corrupted preferences or cache data can prevent iTunes from launching properly or syncing with devices. Resetting settings can clear those issues without removing your content.
Steps to Reset iTunes Preferences:
- Close iTunes completely.
- Navigate to:
C:\Users\<YourUsername>\AppData\Roaming\Apple Computer\iTunes - Rename the file iTunesPrefs.xml to iTunesPrefs.old.xml.
- Relaunch iTunes — it will recreate a fresh preferences file.
This resets your preferences like playback, library location, and store login details but keeps your media safe.
Reset iTunes Cache:
- Inside iTunes, go to Edit → Preferences → Advanced.
- Click Reset Cache under the iTunes Store section.
- Restart the app.
Fix 4: Check Firewall & Antivirus Conflicts
Windows Defender or third-party antivirus programs can sometimes block iTunes components or ports required for device connection and network activity.
Steps to Allow iTunes Through Firewall:
- Open Control Panel → System and Security → Windows Defender Firewall → Allow an app through firewall.
- Click Change settings.
- Ensure both Private and Public boxes are checked for:
- iTunes
- Bonjour
- Apple Mobile Device Service
- Click OK to save.
Temporarily Disable Antivirus:
If iTunes still fails to sync or launch, disable your antivirus temporarily and check again.
If it works, add iTunes and its components to the antivirus exclusion list.
Pro Tip: Re-enable your antivirus immediately after testing — never leave it disabled for long.
Fix 5: Reinstall iTunes Properly
If the repair didn’t solve the issue, perform a clean reinstall. Doing this the right way removes all broken components and registry entries.
Step-by-Step Clean Reinstall:
1. Uninstall iTunes and Related Components
Go to Control Panel → Programs and Features, and uninstall in this exact order:
- iTunes
- Apple Software Update
- Apple Mobile Device Support
- Bonjour
- Apple Application Support (32-bit and 64-bit, if available)
Restart your computer afterward.
2. Delete Remaining Folders
Manually delete these directories (if they still exist):
C:\Program Files\iTunes
C:\Program Files (x86)\iTunes
C:\Program Files\Common Files\Apple
C:\Program Files (x86)\Common Files\Apple
Also remove:
C:\Users\<YourUsername>\AppData\Local\Apple
C:\Users\<YourUsername>\AppData\Roaming\Apple Computer
3. Reinstall the Latest iTunes
Download the official installer from Apple’s website or via Microsoft Store.
Install using Administrator privileges (right-click → Run as administrator).
Restart your system once done.
Note: Avoid using third-party or unofficial versions of iTunes. They can introduce malware or broken dependencies.
Bonus: How to Prevent Future Errors
You can minimize iTunes issues by maintaining your system and following best practices:
1. Keep iTunes Updated
Enable automatic updates or regularly check for new versions.
2. Maintain Windows Health
Use Disk Cleanup, SFC (System File Checker), and DISM to repair corrupted Windows files:
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
3. Regularly Reboot Your PC
It refreshes background services and prevents memory conflicts that cause iTunes lag.
4. Avoid Force-Closing iTunes
Interrupting background sync or updates can corrupt files.
5. Backup iTunes Library
Regular backups save your playlists, ratings, and metadata in case of corruption.
6. Avoid USB Hub Connections
Connect iPhone or iPad directly to your PC’s USB port instead of using external hubs or docks.
7. Use Genuine Cables
Non-certified lightning cables often trigger “Device not recognized” errors.
